PPE HEAVY-DUTY CAST ALUMINUM REAR DIFFERENTIAL COVER

XDP has the PPE Heavy-Duty Cast Aluminum Rear Differential Cover that will increase the fluid capacity in your 11.5” or 12” Axle equipped 2020-2022 GM 2500HD/3500HD. This differential cover is specially engineered to reduce friction and help increase lubrication. Featuring high-quality cast A356.0-T6 aluminum construction, this cover offers durability and maximum heat dissipation.

The PPE Heavy-Duty Cast Aluminum Rear Differential Cover provides increased fluid capacity for greater thermal stamina. The specially designed heat sinks inside this cover and cooling fins on the outside increase its surface area to improve heat dissipation. The cooler the gear oil the remains, the longer it retains its viscosity to extend the service life of the differential. A high-power Neodymium magnet comes with he 304 stainless-steel fill plug that will remove ferrous metals right from the oil before they have the opportunity to do damage.
